FILING AND INnExING EQUIPMENT.

Specication of Letters Patent.

Application filed June -5, 1919. Serial No. 301,886.

'of Boston, county of SuHolk, and State of Massachusetts, have inventedan Improvement in-Filing and Indexing Equipments,

of which the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting` like parts.

This invention relates to filing and indexing equipments of the class inwhich the Sheets are arranged with their identificationreceiving marginsin overlapping relationship, and the invention aims to facilitate theremoval of the sheet-holders'from and their replacement intheirmounting.

My invention will be best understood by reference to the vfollowingdescription, when taken in connection with the accompanying drawings ofone specific. tiling and indexing equipment selected forexemplilication, while its scope will be more particularly pointed outin the appended claims.

In the drawings:

Figure 1 is a front elevation of a filling and indexing equipmentembodying my invention, showing the sheets and sheet-holders in thepositions which they normally occupy;

Fig. 2 1s a front elevation of a portion of the equipment showing theSame arranged preparatory to the removal of the selected sheet andsheet-holder from the'mounting;

Fig. 3 is a sectional view on line 3-3 of Fig. 2;f

Fig. 4 is a sectional view on line 4 4 of Fig. 2;

Fig. 5 is an elevation of one of the sheets and its sheet-holder,illustrating the manner of detaching one from the other; and

Fig. 6 is a plan of one end of a sheetholder illustrating the notchtherein.

Referring to the drawings, and to the embodiment of my invention whichis illustrated therein, I have chosen for exemplification a ling andindexing equipment comprising a plurality of sheets 10, arranged withtheir identification-receiving margins in overlapping relationship, asshown in Fig. 1, each of said sheets being suitably held in asheet-holder which may be of any appropriate Character, but hereincomprises a cylindrical tube 11, provided with a longitudinal slot 12(see Fig. 3), in which the sheet is received, said sheet being suitablyheld therein as by a wire 13 (see Fig. 5), which isreceived within thetube 'and extends through perforations 14 provided in the sheet. Myinvention, however, is by no means limited to a sheet-holderof thisform.

`Herein, the `sheet-holder is. extended at both ends beyond the edgesofthe sheet to form trunnions which are received in suitable guides, inwhich the sheet-holder is mounted ,to turn about lits axis, in anappropriate mounting, herein in theform of a plate 15 whose marginalportions are benttoz form inwardly-turned flanges 16 and 17, formingopposed channels 18 and- 19, best shown in Fi'g. A4. Thesheet-holdersmaintain the lidentiica'ti'on-receiving margins of thesheets in appropriately-spaced relationship, while permitting the sheetsand sheet-V holdersto be swung about their respective axes ther-eby topresent either face of each sheet to View.- This is well illustrated inFig. 3, in which some of the sheets are turned in an upward directionand others in a downward direction.

In aifile or index of this class, it is desirable to rearrange andreclassify the sheets from time to time,'and to make renewals andreplacements. Tozthis end,I have herein made suitable provision wherebyremoval of a selected' Sheet and sheet-holder mayv be accomplishedwithout the necessity of removing any others, and without Shifting anyof the sheets and Sheet-holders lengthwise of the channels in which ytheholders are received. The terminal portions of the sheet-holders arenormally locked in their guides, owing to the fact that they areoverlapped bythe in- Wardly-facing langesl and 17. This is wellillustrated in Figs. 1, 2 and 4. When, however, it is desired to removeagiven sheet and sheet-holder, the sheets are opened at f with a notch 22corresponding in shape to the tongues. As a matter of convenience, inthe present example, both ends of the sheetholder are thus notched sothat they are reversible, and hence either end may coperate with thetongues.

Referring now to Fig. 4, it is apparent that by positioning the sheet ina plane substantially perpendicular to the plate l5, the notches 22 arebrought into registration with one of the tongues 20, and when thuspositioned, the sheet and the sheet-holder may be rocked about the otherend of the sheetholder as a fulcrum into some such position as thatshown in dotted lines in Fig. 4. During this movement, the tongue 20passes through the slot 22, and the sheet-holder is thus unlocked,whereupon it may be withdrawn lengthwise out of the guide at its otherend in an obvious manner. The sheet may now be removed from thesheet-holder, and restored to its place therein, or replaced by another,after which the sheet-holder may be reintroduced into the mounting atany desired point by simply reversing the foregoing operation.

It should now be evident that when the sheets and sheet-holder are inplace and in their normal positions represented in Fig. l, the notchesin the sheet-holders are out of registration with the described tongues,and hence the latter serve to lock the sheetholders in place. Suitableupper and lower 'limiting stops 23 and 24 may be provided to limit theupward and downward movements, respectively, of the uppermost andlowermost sheet-holders, as will be evident from an examination of Fig.1.

Having thus described one embodiment of my invention, but withoutlimiting myself thereto, what I claim and desire by Letters Patent tosecure is:

l. A filing and indexing equipment comprising, in combination, aplurality of sheets having spaced, overlapped margins, a plurality ofsheet-holders, and a pair of guides provided with channels in which theends of saidv sheet-holders are received and mounted to turn about theirrespective axes, said sheet-holders and guides having cooperating meansnormally locking said sheet-holders in said guides but adapted to unlockand permit said sheet-holders to be removed by rotation about their axesto positions. Y

2. A filing and indexing equipment comprising, in combination, vaplurality of sheets havng spaced, overlapped margins, a plurality ofsheet-holders, and a pair of guides predetermined having inwardly facingflanges overlapping,

the ends of said sheet-holders, oneof said -to permit the removal ofsaid sheet-holders by withdrawing one set of ends of the latter throughthe respective notches.

4. A filing and indexing equipment 4cornprising, in combination, aplurality of sheets having spaced overlapped margins, a plurality ofsheet-holders provided with notched ends, a pair ofguides having'inwardly-facing, sheet-holder retaining flanges one of which is providedwith a plurality of spaced tongues normally overlying the adjacent endsof said sheet-holders, the notches of said sheet-holders being movableinto registration with said tongues, thereby to permit saidsheet-holders to be withdrawn.

5. A filing and indexing equipment comprising, in combination, aplurality of sheets having spaced, overlapped margins, a pluraltiy ofsheet-holders provided with notched ends, a pair of guides havinginwardly-facing, sheet-holder retaining flanges one of which is providedwith a plurality of generally V-shaped tongues separated by generallyV-shaped notches, said tongues normally overlying the adjacent ends ofsaid sheet-holders and retaining the same in place, and saidsheet-holders being mounted to rotate to bring their notches intoregistration with said tongues, thereby to permit said sheet-holders tobe withdrawn.

In testimony whereof, I have signed my name to this specification.

JOHN T. QUIGLEY.
